+/**
+ *  Sets up logging for MSIs and then calls the appropriate custom action with argc/argv parameters.
+ * 
+ *  MSI deferred custom action dlls have to handle parameters (properties) a little differently,
+ *  since the deferred action may not have an active session when it begins.  Since the easiest
+ *  way to pass parameter(s) is to put them all into a CustomActionData property and then retrieve it,
+ *  the easiest thing to do on this ( C/C++ ) end is to pull the parameter and then split it into
+ *  a list of parameter(s) that we need.
+ * 
+ *  For this implementation, it made sense to treat the single string provided in CustomActionData
+ *  as if it were a command line, and then parse it out just as if it were a command line.  Obviously,
+ *  the "program name" isn't going to be the first argument unless the MSI writer is pedantic, but
+ *  otherwise it seems to be a good way to do it.
+ * 
+ *  Since all entry points need to do this same work, it was easiest to have a single function that
+ *  would do the setup, pull the CustomActionData parameter, split it into an argc/argv style of
+ *  argument list, and then pass that argument list into a function that actually does something
+ *  interesting.
+ *
+ *  @param hInstall The hInstall parameter provided by MSI/WiX.
+ *  @param func The function to be called with argc/argv parameters.
+ *  @param actionName The text description of the function.  It will be put in the log.
+ *  @return Returns ERROR_SUCCESS or ERROR_INSTALL_FAILURE.
